Filing in context
The Propeller Shaft is the most frequently cited component category in this archive, appearing in 52 of its 4,890 filings. This filing is one of 86 Mitsubishi notifications from 2007 in this archive. For scale, 4,782 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 7 months.
Defect
On large buses equipped with a hydraulic retarder (auxiliary braking device), the structure of the propeller shaft connection (end yoke) is inadequate. The stopper that prevents the cross-joint (spider) bearing from pulling out of the end yoke may wear through repeated stop-and-go operation, or may be damaged during propeller shaft assembly. Continued use causes bearing play to develop, resulting in excessive propeller shaft vibration. In the worst case, the bearing retainer or mounting bolts fracture and the propeller shaft detaches from the vehicle.
Corrective action
On all vehicles, replace the end yoke and spider assembly with the corrected part.

状況
流体式リターダ（補助制動装置）を装着した大型バスにおいて、プロペラシャフト接続部（エンドヨーク）の構造が不適切なため、エンドヨークに設けてある十字継手（スパイダ）のベアリング抜け出し防止用のストッパーが発進停止の繰り返しにより摩耗する、又はプロペラシャフト組立て時に損傷する場合がある、又はプロペラシャフト組立て時に損傷する場合がある。そのため、そのままの状態で使用を続けると、ベアリングにガタを生じてプロペラシャフトが過大に振動し、最悪の場合、ベアリング固定金具又は取付ボルトが折損して、プロペラシャフトが脱落するおそれがある。
改善措置
全車両、エンドヨークとスパイダ一式を対作品と交換する。
